Residual effect of Biochars and their feedstock on growth and yield of Green gram in Acid soils

Abstract: This paper evaluates the comparative residual effect of four types of biochar as well as their feedstocks (biomass material) in presence of 50% recommended dose of fertilizers (RDF) on growth and yield of green gram in acid soils. Soil was treated with four types of biochar and their feedstocks at different doses viz. 0, 2.25, and 4.50 g kg-1 of soil before filling the pots. The mustard was grown as a direct crop (data is not given) and green gram taken as residual crop after harvesting of mustard in same pots with recommended agronomic practices. Biochar application significantly increased the growth and yield of green gram compared with only 50% RDF. Biochar application at the rate of 4.50 g kg-1 along with 50% RDF showed similar results compared with only 75% RDF treatment, but lower than 100% RDF treatments. Lantana biochar (LB) and Parthenium biochar (PB) treatments showed significantly higher growth and yield compared with sugarcane bagasse biochar (SBB) and rice husk biochar (RHB) at both application rates. In general, residual effect of biochar on growth and yield of green gram was at par when compared with their feedstocks at similar application rates. However, growth and yield were obtained with Parthenium biochar, were significantly superior over their feedstock at similar rate of application.
